000014235 520__ $$2eng$$aThe influence of the non-linear behaviour of a crash optimized adhesive in its fracture properties is discussed. The adhesive has been previously analysed by means of standardized TDCB (Tapered Double Cantilever Beam) and MMB (Mixed Mode Bending) tests, which are based on the LEFM (Linear Elastic Fracture Mechanics) theory. In the present study, these tests were modelled numerically. The non-linearity of the adhesive was integrated in the simulations using a spectral viscoelastic law. Crack initiation and propagation were described using the Cohesive Zone Model (CZM) technique. Comparing with the standardized analysis, the results of the simulations showed small decrease of the value of the fracture toughness (GC) when under mode I load and considerable decrease while reaching the mode II load case. These results of the simulations for GC were also used to predict the break force of specially designed specimens tested by means of the Arcan fixture.
